Lavadero literally means 'laundry room' or 'place for washing'. However, in Mexican slang, particularly in the context of parties and drug culture, it can refer to a large amount of money, often illicit, that needs to be 'washed' or laundered.
In this song, the line "que no falte lavadero" (don't let the lavadero be missing) suggests that there should be plenty of money available for the party, implying a lavish and possibly illicit celebration. It's an interesting double meaning that adds a layer of intrigue to the lyrics.
Get ready to party with Grupo Los de la O! "Fuga Pa Cali 2" is all about living life to the fullest, Mexican party style. The song kicks off with the singer ready for a big night out, calling for the band, pretty girls, and plenty of tequila. He's ready to get wild, even mentioning bringing "un quesito fresco" [a fresh cheese] and "los gallos los traigo listos pa darles fuego" [I have the joints ready to light them up] for when sleepiness hits. He wants everyone "bien locos, bien marihuanos" [really crazy, really high] while he's enjoying the music and a girl dancing.
As the night goes on, he's still going strong at "Las dos y media y no tengo nada de sueño" [Two-thirty and I'm not sleepy at all], admitting he might be a bit too energized. He even mentions his girlfriend calling, but he's not interested in drama right now, saying "¿Pa qué la juega, si me conoció borracho?" [Why is she playing games, if she met me drunk?]. He's shutting off his phone to keep the good times rolling, enjoying his hard-earned money, and making sure the band keeps playing until morning. The song paints a picture of a non-stop party with trusted friends, loud music, and even "disparos al viento" [shots in the air] at a ranch. It's a blunt declaration of how he lives his life, fast and without regrets, telling anyone who talks about him, "Yo seguiré siendo el mismo, ya conocen bien mis mañas" [I'll keep being the same, you already know my ways].
